Gradient evaporation type flexible humidification device in plateau low-pressure dry environment

Abstract

The invention provides a gradient evaporation type flexible humidification device in a plateau low-pressure dry environment. The device mainly comprises a water storage and water treatment device, a humidification device, an air supply device and a control system, specifically, tap water is stored in a water storage device after being softened and preheated by a water treatment device, a wet fiber roller blind is driven by a rotating wheel to fully absorb softened water in a water storage tank so as to continuously obtain a large number of wet components, and then under the siphon action of high-speed airflow formed by a fan, after indoor dry air entering the device from an air inlet obtains and carries the wet components through convective mass transfer when passing through the wet roller blind, the indoor dry air enters a room from a humidity conveying opening in a high-speed wet jet flow form. By reasonably controlling the operation parameters of the fan and the opening degree of an air valve, the wet component concentrations are in gradient distribution from high to low within the range from the height of a personnel breathing area to the ground, rollers at the bottom of the device are used in cooperation, efficient and energy-saving local humidification to movable spaces such as gallery bridges, sentry boxes and temporary workstations is achieved, and the device is suitable for extremely dry plateau areas.

Description

technical field [0001] The invention belongs to the technical field of indoor air conditioning, and relates to building a wet environment, in particular to a gradual evaporation type flexible humidifying device in a plateau low-pressure dry environment. Background technique [0002] Due to the special climate conditions such as high altitude and low air pressure in the Qinghai-Tibet Plateau, the indoor air in winter is cold and extremely dry. According to the meteorological data of the Tibet Autonomous Region, the average relative humidity of the coldest month is only 15%, and the lowest relative humidity is 3% to 5%, which is far below the lower limit of human comfort. In addition, compared with normal pressure areas, there is also a large difference in the heat and moisture transfer between the human body and the surrounding environment in plateau areas. When the altitude of the ground rises from 0m to 7000-10000m above sea level, the evaporative water loss of the human bo...
